>>> ... but how you will distinguish fake votes from real ones?

Easy. Serial numbers. Like any other anonymous system (paper money, raffle tickets etc) you assign a number to every valid ballot. Should the same number appear twice, or not appear, then you know something fishy is happening. Any extra fake ballots should be discovered, so long as the originals are not removed from the systems. Throw the numbers around randomly and creating undetectable fakes become very difficult.

The order has to be random or you can trace votes to individuals if you keep the order in which they voted.
In some voting systems (eg, the UK's), this is a feature, not a bug. Ballot serials are recorded against electoral register entries, and the courts have de-anonymized ballots in a few cases.
This is a very serious bug, even if courts want to exploit it.
Most systems seem to have two lines so it's not clear the order people voted in. Excluding hidden cameras which also work with voting machines.
